PAPER MAKING MACHINE Filed J1me 28, 1926' 4 Sheets-Sheet 4 Y/Mu Patented Nov. 5, 1929 UNITED STATES PATENT OFFICE PAPER-MAKING MACHINE Application filed June 28,

This invention relates to paper making machines and more particularly to the deckles employed therewith for preventin the stock in its liquid state from running the edges 6 of the F ourdrinier wire.

In Fourdrinier paper making machines the deckles have heretofore generally consisted of endless straps passing around pulleys, the

lower part of the strap in extending from 10 onepulley to the other also resting on and along the wire so as to be propelled by and travel with the wire. It has been the practice to run these deckles along the wire, to a point past the first or in some cases past the second, suction box; and then to return them.

This stretch of wire from the slice'to the first or second suction box is known as the forming surface of the wire; and thus it correctly states what has been the common practice heretofore to say that the deckle straps extend from the breast-roll a distance equal to at least that of the so-called forming surface of the wire.

I have discovered, however, that the length of contact of the deckle straps with the wire may be shortened to a very material extent; the fact being, as I have discovered, that the web or sheet of paper stock forms an edge sufliciently coherent or self-retentive to permit dispensing with deckles, when the web has travelled a distance considerably less than the length of the so-called forming surface of the wire. It follows that the length of the deckle straps may be very materially reduced with no detriment to the web of paper in process of formation, and, on the other hand, with important advantages in the saving of cost of construction and operation. In other words, according to the present invention, the distance which the deckle straps extend along the wire is considerably shortcned, preferably to the extent attained by terminating the engagement of the straps with the wire approximately at the point :5 Where the web or sheet has reached such stage of formation that its edges will hold. This point of terminating the deckle may vary somewhat with conditions, such as the particular characteristics of the paper stock being employed, but in any event the length.

of the deckle heretofore considerably less than that of deckles heretofore commonly used, whileat the same time being of sufiicient length to keep the stock from flowing off the edges of the wire prior to formation of the web. What this means practically is that, by means of the present invention, the length of contact between the deckle straps and the wire may be reduced to a half, or a third, and in some cases to even a quarter, of what is now common in mill practice.

I have also discovered that deckle straps, although resting upon and being supported by the wire, need not travel forward with the wire, but on the contrary may be fixed against such participation in the forward movement or travel of the wire. Therefore, according to the present invention, it is proposed to anchor or fix the deckle straps against forward movement with the wire, and furthermore to dispense with the continuous double reach or double length deckles running from one pulley to another and to employ instead what may be termed single reach or single length deckle straps each extending along and resting upon and being supported by the wire and preferably anchoredv at its end nearest the slice.

As thus appears,in contrastto deckle straps heretofore commonly used, some of the advantages and objects attained by the present invention are the provision of deckle straps which are shorter in the length thereof in engagement with the Fourdrinier wire; which are single reach straps instead of double reach continuous straps such as used with pulleys; which require less material and hence are much lighter and cheaper; which require fewer mechanical parts in the makin andinstalling of deckle equipment; and w ich can be fixed against traveling movement with the Fourdrinier wire while at the same time being supported on and by the traveling wire Without excessive friction, this being made possible largely by the reduced length and weight of the deckle straps. Other objects attained are reduction in mass and Weight of deckle strap equipment to be vibrated with the wire by the shake motion; and the possibility of applying deckle straps of this in- Fig. 1 is a perspective view of part of a Fourdrinier paper-making machine equipped with deckle straps in accordance with the present invention;

Referring first to the embodiment of the invention shown in Figs. 1 to 4, 5 is the Fourdriner wire passing over table rolls 6, 6, around breast roll 7, and under stretch roll 8, at the wet end of the machine. The table rolls and breast roll are journalled in any suitable manner on a spring-supported shake frame which includes the yoke 9 and the shake rails 10, 10 pivotally connected to said yoke at 11, 11. The shake frame is vibrated laterally of the machine by a shalre motion (not shown) which is'connected to said frame at 12 by a connecting rod 13, as shown in Fig.

,3. A flow-box 14 has secured to the front wall thereof an apron-board 15 having attached thereto a flexible apron 16 which projects over the Fourdrinier wire 5 at the breast roll 'Z' and is slightly spaced from the-wire. A

menses pair of pond plates 17, 17 are positioned against the front wall of the flow-box 14 at opposite ends thereof, respectively, each plate being adjustably secured in place by a wing bolt 19 passing through a slot 21 of the plate. A bracket 18 is secured to each pond plate 17, and said bracket is adjustably secured to the apron-board 15 by means of a wing bolt 20 passing through a slot 22 of said bracket 18. A pond wall 28 is adjustably secured to each bracket 18 by two wing bolts 24, 24 passing through slots 25", 25 of the bracket. At their outer ends the pond walls 23, 23 are connected to deckle frames 25, 25 respectively, as by bolts 26, 26, which bolts also serve. to secure bracket arms 27, 27 to the deckle frames. On each-of the arms 27, 27 there is a stud shaft 28 (Fig. 2) which carries a pulley or wheel 29 such as ordinarily heretofore used with continuous deckle straps. The slice under the lower edge of which the stock flows onto the wire is formed of two plates or sections 41, 41, the outer ends of which fit against the inner surfaces of the pond walls 23, 23, respectively, said plates at their inner ends overlapping each other and being adjustably secured together by wing bolts 42, 42 on one plate passing through slots 43, 43 of the other plate. The lower edge of the slice, that is the lower edges of plates 41, under which the liquid stock is delivered, curves forwardly and outwardly, said edges being flexible and thereby adjustable to deliver thereunder the desired uniform thicknessof flow of stock. Each pond wall 23 has on its inner face a bracket 44. A strut bar formed of two telescoping sections 45, 45 is secured at its opposite flattened ends 46, 46 to said brackets 44;, 44 by set screws '47, 47 threaded through arms 48, 48 of the brackets 44, 44 respectively, said set screwspassing through said flattened ends of the strut bar. Each set screw 47 has two lock nuts 49, 49 positioned respectively above and below the flattened end 46 of the strut bar, thereby securing the latter in any desired position of vertical adjustment on the set screw. The sections or plates 41, 41 of the slice are made of flexible metal orother suitable material to provide for warping or bending of their lower edges 50, 50 thereby to deliver onto the wire 5 a flow of stock of the desired uniform thickness corresponding to the entire width of the web of paper to be produced. Warping or bending of said lower edges 50, 50 of the slice sections is eflected by means such as the series of bolts 51, each pivotally connected at its lower end at 52 to a plate 53 secured to the extreme lower edge 50 of the slice. Each bolt 51 has a threaded upper end which passes loosely through a suitable opening in the strut bar and is en gaged by a nut 54, the turning of which will raise or lower its bolt 51. A look not 55 on each bolt 51 below the strut bar 45 secures the bolt in position to which it is adjusted to pro= bevel gear 38.

duce the desired warping of the lower edge of the slice. Brace arms 56, Fig. 1, are secured at one end to the outer face of sections or plates 41, 41 of the slice; at their outer ends said arms 56 have openings through which the bolts 51. pass respectively.

The deckle frames 25, 25, pond walls 23, 23, pond plates 17, 17, and the slice composed of plates 41, 41, are all adjustable transversely of the machine according to the particular width of web or sheet which it is desired to produce. In providing such adjustment, each deckle frame has secured thereto two sleeves 32, 32 slidably mounted on tubular bars 33, 33, res ectively, said bars extending transversely o the machine through open ings in the deckle frames and at their opposite ends being supported by pillars 34, 34; mounted on longitudinal sill pieces 35, 35 of the machine base. A pair of shafts 36, 36 extend into the opposite ends respectively of the tubular bars 33, 33, the inner screwthreaded ends of said shafts engaging threaded openings respectively of a pair of blocks 36, 36 positioned within said tubular bar. The lower end 36 of each block 36 extends through an elongated slot on the under side of its tubular bar 33 and is rigidly secured to the corresponding. sleeve 32, thereby providing for inward and outward movement or adjustment of said sleeves, and of the deckle frames to which they are secured, by rotation of the shafts 36. A bevel gear 37 fixed to each shaft 36 meshes with a The two bevel gears 38, 38 at one side of the machine are fixed to a shaft 39, and the two bevel gears 38, 38 at the other side of the machine are similarly fixed to another shaft 39. Rotation of one shaft 36 at one side of the machine by a crank handle 40 thereon imparts like rotation to the other shaft 36 at that side of the machine through the bevel gears 37, 38, and shaft 39, A similar crank handle 40 on one of the shafts 36 at the other side of the machine serves in like manner to rotate both shafts 36 together. By such means the parts can be adjusted from or toward each other according to whether it is desired to increase or decrease the width of the aper web to be produced.

The parts of the mechanism thus far set forth in the detail description being generally of construction well known in the practical art, further description thereof herein is unnecessary.

As well known, deckle straps as heretofore commonly employed consist each of a continuous band or strap of rubber material extending-over pulleys at opposite ends thereof, the lower side of the continuous stra between the two'pulleys extending from the s ice along and in engagement with the Fourdrinier wire to a point beyond the first and frequently beyond the second suction box. By such engagement of strap and wire, the longitudinal or forward movement of the wire is transmitted to the deckle strap and the pulleys rotate as the strap travels with the wire. In the embodiment of the present invention shown in Figs. 1 to 4;, two deckle straps are shown at 30, 30. Each strap may be made of the usual rubber material and of the usual dimensions in cross-section. But instead of the usual continuous double length strap, each deckle strap 30 is of single length or reach, rests upon, is supported by, and extends along the wire, but is fixed or anchored against participation in the longitudinal-movement of the wire. Furthermore, instead of extending along the wire a distance approximately equal to'what has heretofore been known as the forming surface, that is, to the first or second suction box, each deckle strap 30 of this invention is much shorter, being terminated at approximately the distance from the slice at which the edges of the web or sheet will have sufiiciently formed so that the stock will not run off the edges of the wire, or in other words, will have formed suiticiently not to require thereafter the presence of deckle straps. That is to say, according to this invention, the deckle straps, whether of the single or the double reach type, instead of extendin from the breast roll to a point beyond the first or the second suction box (as those boxes are ordinarily placed in a Fourdrinier machine) extend only to a point that is a substantial distance short of the first suction box. Such shortening of the length of engagement of the strap with the wire, as well as the use of a single reach or single length strap in contrast to the usual continuous double reach and hence double length strap, not only effects a considerable saving in quantityv of material used in producing the straps, but also materially reduces bulk and weight of the straps to such an extent as to enable the wire to support the straps entirely without undue strain upon the wire or frictional resistance to its forwardlmovement.

As shown in Figures 1 to 3, the machine has the usual equipment of pulleys such as 29 for endless deckle straps such as heretofore used. The deckle strap 30 at one end extends partly around pulle 29 with said end secured to the pulle b a 0 am 57 engaged over the strap and tile elly of t e pulley and held in position by a set-screw 58 and lock-nut 58. The pulley 29 is shown as being held against rotation by a set-screw 59. threaded through hub 60 of the pulley into enga ement with the stud shaft 28. A pin 61 on racket 27 is also shown as standing in the ath of one of the spokes 62 of the pulley, t us serving as a further means for reventing rotation of the pulley and anchoring the strap 30 at one end to prevent it from participating in the forward movement or travel of the wire. From its point of anchora e to its pulley,

each deckle strap extends a ong the surface of the wire approximately under its corresponding deckle frame 25. The weight of the straps and their engagement with the traveling wire will maintain them in approximate parallelism with eachv other from end to end. Adjustments of the deckle frames 25 and other parts for narrower or wider webs of paper will be communicated to the deckle straps.

In the embodiment of the invention shown in Figs. 5 and 6, the adjustable pond walls, deckle frames, and parts connected therewith, are dispensed with, the flow-box 14 being provided with rigid pond walls one of which is indicated at 63. The slice in this instance comprises a single plate 64 which extendsacross the entire width of the pond and is mounted on said rigid pond walls. The plate 64 has riveted or otherwise suitably secured to the lower edge thereof a relatively wide intermediate flexible slice element 65 arcuate-shaped in cross section, and a plurality of narrower flexible slice elements 66, 66 of like configuration disposed in end to end abutting relation at both ends of the intermediate flexible slice element 65. Short single reach deckle straps 67 are employed, and are supported on the wire 5. Each strap has a reduced end portion 68 which may be clamped between any one of the flexible slice sections and the flexible apron 16 by means of the proper bolt 51 and its adjusting nuts 54 and 55 in cooperation with strut bar 45 As shown in Figs. 5 and 6, the end 68 of the deckleis clamped under one of the narrower flexible slice elements 66, the others 01? which bear on the apron 16 so as to form a dam and prevent the stock from flowing past any portion of the slice extending outwardly from the deckle 67. The stock thus flows under the slice element 65 and is confined on the wire by the deckles. With this arrangement, the

deckles may be adjusted laterally of the machine b hand in order to obtain a web in sheet 0 the desired width, the end 68 of the deckle being clamped between the flexible apron 16 and the flexible slice element which is located in line with the deckle after its adjustment. When the desired adjustment of the deckles has been obtained, the flexible slice element or elements disposed outwardly of the deckles are depressed into engagement with the apron while those disposed betweenthe deckles-are lifted to rovide the required opening for the flow 0 stock onto the wire. The end 68 of each deckle is preferably held in engagement with the rear curved surface of the slice by a clip 68' riveted or otherwise suitably secured to the slice. Warping or curving of the lower edge of the slice may be eflected as before described, to provide a flow of stock which is uniform in thickness across the entire width of the web to be formed.

Instead of employing deckles with straight ends, such as shown in Figs. 1 to 6, deckles with lL-shaped ends may be em loyed as illustrated in Figs. 7 and 9 to 11. n such use of deckles with L-shaped ends, additional clamping devices are preferably provided for secur ing the ends of the deckles between the flexible apron 16 and flexible slice. As shown in Figs. 7 and 8, each additional clamping device comprises a bail 69 mounted on one of the plates 53. For this purpose the clip is provided at the rear thereof with apertured bosses 70, 70 in which-are journalled the free ends 71, 71 of the bail, and the sides 72, 72 of the bail are normally engaged under lugs 7 3, 73 on the sides of the plate. The front of said bail is formed with spaced yokes 74, 74 and an intermediate yoke 75, the yokes 74, 74 engaging across the edge of the L- shaped end of the deckle, and the yoke 7 5 constituting a finger pull for disen aging the bail from the deckle and lugs 73,

In the embodiment shown in Fig. 9, the plate 53 is secured to the lower edge of the flexible slice by a rivet 76 provided with a conical head which embeds itself in the L- shaped end of the deckle when the edge of the flexible slice is depressed by the bolt 51.

1n the embodiment of the invention shown in Figs. 10 and 11, the short single reach deckle strap 78 has an L-shaped end providing a pull strap 79 which serves as means for manually adjusting the deckle laterally of the machine. When the desired adjustment of the deckles has been obtained, the strap 79 of each deckle is clamped between the flexible apron 16 and the lower edge of a single-piece flexible slice 80, thus preventing movement of the deckle with the wire 5 and preventing the stock from flowing beneath any portion of the slice outside of the deckles.

. As shown in Figs. 12 and 13, the short single reach deckle strap 81 has secured to the angular portion 82 of its L-shaped ends a block 88 of wood or other suitable material. The portion 82 of the deckle is secured to the front edge of the block by a screw 84 and the surface of the block rearwardly of the slice 85 is curved to fit the latter. as means for manually adjusting the deckle laterally of the machine and, after the desired adjustment has been made, the block of each deckle acts as a dam to prevent the stock from flowing beneath any portion of the slice outside of the deckles. At the same time the deckle 81 supported on the wire 5 is prevented from moving with the latter by the block 83.

In the embodiment shown in Figs. 14 and 15, an angular re-enforci'ng bar 86 is secured in any suitable manner to the lower edge of a single-piece flexible slice 87. On each end of the bar 86 is secured an angle bar 88, the

connection for which with the bar 86 is provided by wing bolts 89, 89 on bar 86 passing through slots 90, 90, in the bar 88. The

The block 83 serves mamas deckles 91, 91 are comprised by single reach straps supported on the wire 5 and at one end.

secured, respectively, to the inner ends of the angle bars 88, 88 by brackets 92, 92. Through the medium of the wing bolts 89, 89 and slots 90, 90, the deckles 91,91 may be adjusted manually toward and from each other to produce a web of any desired width, the angle bars 88, 88 preventing the flow of stock beneath any portion of the slice outside of the deckles 91, 91 and, together with the brackets 92, 92, serving to anchor the deckles against movement with the wire 5.
